<h3>SYNOPSIS</h3>

<p>
InnoDB Plugin views: informational views on InnoDB Plugin. 
<ul>
	<li><a title="innodb_locked_transactions" href="innodb_locked_transactions.html">innodb_locked_transactions</a>: List locked transactions, the locks they are waiting on and the transactions holding those locks.</li>
	<li><a title="innodb_simple_locks" href="innodb_simple_locks.html">innodb_simple_locks</a>: Listing of locks, simplifying INFORMATION_SCHEMA.INNODB_LOCKS</li>
	<li><a title="innodb_transactions" href="innodb_transactions.html">innodb_transactions</a>: Listing of active (InnoDB Plugin) transactions, which are currently performing queries</li>
	<li><a title="innodb_transactions_summary" href="innodb_transactions_summary.html">innodb_transactions_summary</a>: A one line summary of InnoDB's transactions: count, state, locks </li>
</ul>
</p>

<h3>DESCRIPTION</h3>
<p>All views in this category require 
InnoDB Plugin to be installed along with all related INFORMATION_SCHEMA plugins.
</p>

<p>
If you are using MySQL >= <strong>5.5</strong>, then you are using InnoDB plugin (and it is simply refered to as plain InnoDB). 
</p>
<p>
If you are using MySQL <strong>5.1</strong> then you are either using the "old", built-in InnoDB, or, upon proper configuration,
the InnoDB Plugin. See <a href="http://dev.mysql.com/doc/refman/5.1/en/replacing-builtin-innodb.html">this page</a> from the manual 
for InnoDB Plugin setup for MySQL <strong>5.1</strong>.
</p>

<h3>EXAMPLES</h3>
